servants of Christ Jesus: Paul and Timothy belonged entirely to Christ and were fully devoted to his service (see Philippians 2:20–21).
God's holy people are made holy in God's sight by Christ's redeeming work (see Ephesians 1:4, 7; 5:25–27; Colossians 1:22). They are being made holy by the transforming work of the Holy Spirit in their lives (compare Philippians 4:21).
Philippi was a Roman colony in the province of Macedonia. The church in Philippi was the first Christian community in Greece (see Acts 16:11–40).
In the early church, church leaders provided spiritual guidance, while deacons attended to practical matters (see 1 Timothy 3:1–13). There were no professional pastors or priests like there are today (compare 1 Corinthians 14:26–31).
